COIN-TESTING MACHINE.

Specification of Letters Patent.

Patented May 5, 1908.

Original application filed. June 22, 1906, Serial No. 322,904. Dividedand this application filed March 27, 1907. Serial No. 364,774.

To all whom it may concern:

Be it known that I, lVIORGAN D. SADTLER, citizen of the United States ofAmerica, and resident of the city of Baltimore, State of Maryland, haveinvented certain new and useful Improvements in Coin-Testing Machines,of which the following is a specification.

My invention relates to certain new and useful improvements in cointesters adapted to be used in connection with coin controlled machinesof all types.

The invention described and claimed. in the present application is shownand described in my co-pending application Ser. No. 322,904, filed June22, 1906, and this application is a division thereof.

In the above referred to application I have shown and described a cointester which will test the coins for size, diameter, thickness andcharacter of metal.

The present application covers that part ofthe machine shown anddescribed in the above referred to application, which tests the coins todetect slugs made of material which can be detected by a magnet. That isto say, the present application relates to a magnetic testing device.

Referring to the drawings wherein I show the preferred form of myinvention and wherein the same part is designated by the same referencenumeral wherever it occurs, Figure 1 is a perspective view of themagnetic tester. Fig. 2 is a longitudinal section of the case showingthe testing mechanism in side elevation. Fig. 3 is an end view showingthe case in section with the operating parts in elevation and in theirnormal position. Fig. 4 is a view similar to Fig. 3, showing the partsin the position they occupy at the-limit of movement of the mechanismduring the testing operation. Fig. 5 is a detail view of the hingedmembers of the coin guide. Fig. 6 is a detail perspective view of theoperating shaft showing attached thereto the bail for clearing themagnets.

1 designates a rectangular case shown as provided with a cover 2 havingslots 3 formed therein for the insertion of coins.

4 designates a pair of side frames which are secured to a base 5. Theseside frames,

preferably and as shown, are provided with means by which the case 1 maybe secured thereto to inclose the testing mechanism.

6 designates a shaft journaled in bearings in the side frames 4, andprovided at one end with an operating handle 7 which is located outsideof the casing 1.

8 is a flanged disk which is shown as secured to the outside of one ofthe frames 4, and through which the shaft 6 loosely passes. To theinside of the flange of this disk is secured one end of a clock spring9, the other end of the clock spring being secured to the shaft 6whereby the spring will operate to return the shaft to its normalposition, as

soon as the handle is released after the operation of the machine.

10 designates a plate extending between the side frames 4 and over theshaft 6, the plate being shownas secured to the top of the side frames4. To the upper surface of this plate I secure a series of magnets 11,one magnet being arranged under each of the slots 3.

12 is a plate covering all of the magnets except their operative ends,which plate and the magnets are held in position by means of the screws13.

The magnets are shown as being horse shoe magnets and the ends of thehorse shoes are so located as to be closely adjacent to the path of acoin or token as it passes down from the slots 3 into the machine. Fromthis it will be seen that any iron washer or other slug capable of beingattracted by a magnet will be stopped by the magnet under the slot inwhich it is inserted, and thus prevented from entering the machine and,possibly, operating the same.

14 designates a plate which extends from one end of the case to theother and located near the top of the case. This plate is provided withcoin slots 15 which register with the slots 3 in the top of the case.

16 is a guiding flange which extends down from the top 2 adjacent to theslots 3 to the top of the plate 14 beside the coin slots 15, whereby acoin dropped in a slot 3 is guided into the particular slot 15 locatedjust below the same.

17 is a late which forms a coin guide and is pivote at 18 to the ends ofthe plate 14. This plate is adapted to guide the coin or token past theends of the horse shoe magnets 11 and down into the other part of the machine.

19 is a spring one end of which is connected the side frames.

to the guide plate 18 and the other end to the side of the casingwhereby'the plate is held normally in position to guide a coin or tokenin its proper path.

In order to clear the magnets of a slug which may be caught by them Iprovide a.

rod or bail 20 which has its ends 21 bent inwardly at right angles andsecured to the shaft 6, preferably and as shown, by passing the endsthrough openings formed in the shaft and holding them in position bymeans of the nuts22. The ends 21 of the rod or bail are of such a lengththat its main portion 20 will pass over the tops of the magnets andclose thereto, in order to knock off the magnets any slugs which may beheld thereon.

23 is a wing cam mounted on the rod 20 at one end of the right anglebends, and this wing cam is adapted to engage a projecting end 24 of thehinged guide 17. The hinged guide is preferably of suflicient length toextend outside the side frames, and is provided With slots 25 wherebythe guide may straddle From this it will be seen that the wing cam willmove the guide, when the operating shaft 6 is turned, out from in frontof the magnets so that the rod 20 can remove a slug held by the magnets.

26 is a chute formed in the side of the easing 1 and located in such aposition as to catch a slug knocked off the ends of the magnets by therod or bail 20.

27 is an arm mounted on the shaft 6 and adapted to contact with stops 28mounted on the side frame 4, whereby the revolution of the shaft 6operated by means of the handle 7 in one direction and by the s ring 9in the other, is limited to substantially half a revolution.

In this application I have not described the testing disks shown,described and claimed in the parent application of which thisapplication is a division, as such disks are not claimed in thisapplication and form no part of the invention covered by thisapplication. It being understood that the coin or token after passingthe magnets may, as far as this invention is concerned, pass to testingdisks as shown in the parent applica tion, or to any other form oftesting device, or the coins, if desired, may pass directly into a coinoperated machine without being further tested.

While I have described what I believe to be the preferred form of myinvention, I desire to have it understood that many changes may be madein the form, construction and arrangement of parts, and other elementsmay be substituted for those here shown and described, for the purposeof carrying out the function of the elements, without departing from thespirit of my invention, and that where I use the term means in theclaims of this application, it is to be understood that this term coversall forms of mechanism which are capable of performing the functionascribed to the term in the claims.

Having thus described my invention what I claim as new and desire tosecure by Letters Patent is: j j I ,i

In a coin testing machine the combina-' tion with a plateprovided'with' an opening through which a coin may be inserted, a secondplate hinged beneath said first mentioned plate and adapted to form ameans for guiding the coin dropped through the coin slot, a magnetlocated adjacent to the hinged plate, said magnet being so located thata coin will pass between it and the hinged plate,- a rotatable shaft andmeans carried by the shaft for moving said hinged plate from in front ofthe magnet, and means adapt-ed to clear the magnet of any slug which maybe attracted thereby.

2. In a coin testing machine the combination with the magnet, of'movablemeans for guiding a coin adjacent to the ends of-the magnet, whereby aslug will be caught by the magnet, a shaft a bail carried'by the shaft"and adapted to be moved past the ends of the magnet by the operation ofthe shaft, whereby any slug held by the magnet will be removed therefromand means carried by the bail for moving the guiding means out of its 1normal position before the bail passes the ends of the magnet.

3. In a coin testing machine the combination with a plate, provided withan opening through which the coin may bepassed, al magnet below saidopening with its ends adjacent to the path of a coin entering saidopening, a guide 0 posite the ends of the magnet and adaptet to guide acoin close to the ends of the magnet, a magnet clearing device, andmeans carried by the magnet clearing device for moving the guide out ofits normal position before themagnet clearing device passes the endsofthe-magnet.

4. In a coin testing machine the-combination with a magnet, of a movableguide 10- cated adjacent to the magnet and adapted to guide a coinbetween it and the magnet, a magnet clearing device adapted to passoverthe magnet and means carried by the magnet clearing device for movingthe guide out of its normal position before the clearing device haspassed over the magnet, whereby any slug held by the magnet may beremoved therefrom.
